Answer» 1. Moment of inertia of a thin rod of length L and mass M about an axis passing through its centre and perpendicular to its length is, I = \(\frac {ML^2}{2}\) 2. Moment of inertia of a circular ring of radius R and mass M about an axis passing through the diameter is,l = \(\frac {ML^2}{2}\) Moment of inertia of a circular ring of radius R and mass M about an axis passing through the centre and perpendicular to its plane is, I = MR2. 3. Moment of inertia of a cylinder of radius R and length L and mass M about an axis passing through the axis is I =\(\frac {ML^2}{2}\) 4. Moment of inertia of a solid sphere of radius R and mass M passing through the diameter is I = \(\frac {2}{5}\)MR2. |
